The Chrome OS Beta channel has been updated to R11 release 0.11.257.44 including the new Chrome 11 Beta, new trackpad and several stability and functional improvements over the previous release. This release contains the following fixes:

We are now running Flash Player on a new platform known as Pepper/PPAPI by default, which we hope will improve stability and performance. It is also running inside a full sandbox which further protects users from malware and security exploits.

An NPAPI version of Flash Player is still included, but not used by default. If you experience significant problems or incompatibilities with the (default) PPAPI version, you can switch to the NPAPI version using chrome://plugins.

Seems that square button IS, in fact, te new window switcher UI. All it does is toggle another window if you have more than one window open. It does the same thing as the "next window" button on the keyboard, the one to the lext of the "reduce brightness" button.

Any more detail about GSM support update? I am living in Hong Kong and the previous hard-coded APN setting in the source code doesn't include my carrier. The feature still need to be enabled in developer mode? Any UI related to the feature updated too?

really dislike this update, mostly because the webcam can't be seen by websites like Facebook, and the tap-to-click has been disabled (had to go back into settings to re-enable it.) Also, the software button for the switching windows is superfluous, because the hardware button does it faster. :(
